a = 1; b = 13; c = +25;
Δ = b2-4ac
Δ = 132-4·1·25
Δ = 69
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(13)-\sqrt{69}}{2*1}=\frac{-13-\sqrt{69}}{2}
$


$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(13)+\sqrt{69}}{2*1}=\frac{-13+\sqrt{69}}{2}
$
